Question

one angle of a parallelogram is 60 degree then find the measure of all the remaining angles .​

Answer 1

Answer:

Step-by-step explanation:

One angle is 60°

Lets consider a parallelogram ABCD

<A =60° {given}

<B =180-60= 120° {adjacent angles are supplementary (<A+<B=180°) }

<C =60° {Opposite angles of a parallelogram are same (<A=<C) }

<D =120 {Opposite angles of a parallelogram are same (<B=<D) }

<A=60°

<B=120°

<C=60°

<D=120°

please mark me as brainliest answer.

Answer 2

Answer:

Step-by-step explanation:

interior angle of a quad=360

60+60+2x=360

120+2x=360

2x=360-120

2x=240

x=120

therefore the four angles are 60,60,120 &120
